Document Summary
Immune system is part of a complex communication network that includes the nervous and endocrine systems - psychoneuroimmunology. In ammation is a disease created by the immune system to stop bacteria - some bacteria are good like in the gut. Consists of - lymphoid tissues, immune cells and chemicals that coordinate and execute immune functions: depend on cell cell communication. Contact dependent signaling that relies on cells binding to surface receptors on other cells. Immunogens that react with products of the response are called antigens. If mechanisms distinguishing self from non self fail the immune system attacks its own cells - autoimmune disease (like type 1 diabetes mellitus: proteins made by immune cells destroy pancreatic beta cells.
